The purpose of acclimation is simple: the water that the fish or corals are packaged in has different temperature, pH, and salinity parameters than your aquarium. Fish, and especially invertebrates, are very sensitive to even minor changes in these parameters, so proper acclimation is the key to ensuring their successful relocation.
We recommend either of the two acclimation methods explained below, and wish to remind you the acclimation process should never be rushed. Also, remember to keep your aquarium lights off for at least four hours after the specimens are introduced into the aquarium to help them further adjust.
Though not a requirement of our acclimation procedures, we highly recommend that all aquatic life be quarantined in a separate aquarium for a period of two weeks to reduce the possibility of introducing diseases and parasites into your aquarium and to ensure they are accepting food, eating properly, and are in optimum health before their final transition to your main display.
Turn off aquarium lights.
